Absolute reductions in fossil fuels -- cutting total coal use by 60%, oil by 40% and natural gas by 30% - are clearly required. That means we can't turn to natural gas as a "bridge fuel," as some people advocate. It also rules out the "all-of-the-above" strategy we often hear about from politicians.

In the voluminous annals of dirty energy denialism and flat-out falsehoods, this interview with Greg Boyce, the CEO of America's largest coal company, Peabody Energy, has got to rank up there. Here are a few whoppers by Boyce that jumped out at us.

Vassilis Nikolopoulos is CEO and co-founder of Intelen, Inc, a New York-based emerging startup focused on smart grid big data applications and energy analytics/engagement. I had a chance to catch up with him a few weeks ago at Greentech Media's Grid Edge Live conference in San Diego.

Many factors played a role, but the fundamental differentiator is this: isolating a need and applying just enough technology to solve it, rather than inventing something impressive and then trying to find a market.

We agree with the conclusion reached by PV Magazine, that although growth in renewable power in the United States is increasingly driven by non-RPS factors, "[t]his does not mean that RPS policies are not important."

Here are some key points from a new study by the Brattle Group for NRDC, entitled "Advancing Past 'Baseload' to a Flexible Grid," which argues that far from being a problem, a higher share of clean energy is actually a great opportunity for a wide variety of reasons.

In sum, the future looks extremely bright for clean energy, and for cleantech more broadly. The question isn't whether these sectors will grow rapidly, but simply how rapidly they'll grow. On that, we'd argue that EIA is far too conservative (or pessimistic, if you prefer), while BNEF is quite possibly too conservative as well, although they appear to be much closer to the mark than EIA's typically bearish-on-renewables, bullish-on-fossil-fuels forecasts.

According to a new report by the Energy Storage Association (ESA) and GTM Research, the U.S. energy storage industry is on fire, having just "deployed 71 MW of energy storage in Q1 2017...up 276% from the 18.9 MW deployed in Q1 2016," and with a lot more growth on the way.

See below for video of Chris Brown of Vestas, keynoting the opening session on day two of WINDPOWER 2017, concluding today in Anaheim, CA. According to Brown, who is completing his tenure as Chair of the American Wind Energy Association (AWEA), the next five years will be the "best five years of your life" for the wind power industry.

But wind and other major cleantech sectors rely on distribution-only or distribution-mostly strategies that leave most of the marketing communications (“marcom”) power of these tools on idle. This year, we looked at why that happens. A few external drivers explain a lot.
